HA-609A Dual Mono/Stereo Compressor/Limiter

The HA-609A Dual Mono/Stereo Compressor/Limiter plugin brings the legendary diode bridge compression sound to your DAW with modern modelling accuracy. Heritage Audio has captured every stage of the original circuit, from gain reduction to harmonic response, using discrete Class A topology and three Carnhill St Ives transformers per channel. A fast attack mode for both compressor and limiter adds flexibility for today’s productions. This plugin excels at adding punch, density, and control to drum buses while keeping transients powerful and musical. On the mix bus, it delivers the glue and cohesion that makes a mix feel finished without collapsing dynamics. Vocals stay forward and authoritative without sounding squeezed, and guitars gain thickness and stability. Whether you’re a hobbyist or seasoned producer, the HA-609A offers the weight and musical response that shaped countless records, now with workflow-ready features for FL Studio, Ableton, or Logic.
